shematic is in your mail.
Also I have a BackUPS Pro 650ipnp model.
Main transformer is getting so hot (for about 15 minutes of work in mains mode)that you can't hold finger on it for more than a few seconds.
This model is similar to that in shematic.
Seems that output winding is always connected to mains in mains mode. In inverter mode it is separated from mains.
Otherwise it works ok (or seems so).
Did you experienced any similar problem?

Tom, Can you send me a copy of the APC UPS schematic

Hi Tom -- Same story. I too have 3 of these units at home. Two are working and one is not. Could you please send me a copy of the schematic also as I would like to get the third one up and running.

Thanks, Jack

APC BACK UPS 250i/ 400i/ 600i Schematic

No score for this post

I found the schematic for the APC BACK UPS 250i/ 400i/ 600i! It can be downloaded at http://tibor56.hyperlinx.cz

!!!!!!!!!!!!! USE AT YOUR OWN RISK! !!!!!!!!!!!!

WARRING: THIS DOES LOOK LIKE A UPS SCHEMATIC BUT THERE IS NO TITLE BLOCK, DEVICE NAME OR MODEL ON THIS SCHEMATIC.

UPS UNITS HAVE HIGH VOLTAGE AND HIGH CURRENT BATTERIES IN THEM! BE CAREFUL WHILE SERVICING!!!

!!!!!!!!!!!!! USE AT YOUR OWN RISK! !!!!!!!!!!!!

You will have to register with a user name & password but it is FREE. This site is not in english but there is a login link in the upper right corner and it is easy to see where to enter the registration info. Once registered, there will be icons in the second column that link to the file.

The file to look for is APC BACK UPS 250i_400i_600i sxems.pdf

Have fun!

Does anyone know where to get parts (new or second hand) for APC UPS's? I repair these and I have found that a common problem is the current sensor at the rear going open. This causes the UPS to show zero load regardless of what is connected to it.
Anyone know where to get this part as APC are very unhelpful.
